MUSIC-SHEET-BEGULATOR THROW-OUT.

Specification of Letters Patent.

Patented June 11, 1918.

To all whom it may concern:

Be it known that I, ROBERT A. GALLY, a citizen of the United States, andresiding at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in MusicSheet-Regulator Throw-Outs, set forth in the annexed specification.

In applicants prior Patent #1,093,046 is the broad invention of means toalternately make effective either automatic means or manually controlledmeans of a web guiding device, and one particular form was thereinshown. The present invention shows another desirable form for use withmany styles of web guiding or automatic tracking devices, and especiallyso with the novel form of automatic tracking device illustratedherewith, but which tracking device per 86 is a part of a priorapplication #186229 filed August 14th 1917. The present application alsosets out an extra feature whereby the detector fingers of the automaticdevice are thrown out of contact with the edges of the music during theuse of the hand regulator, thereby avoiding interference and frictionfrom the combined action of the two means at one time.

In the drawings Figure 1 is a front view of a music roll apparatus andcombined automatic tracking device and hand roll regulator, the handregulator thrown out of use, and the automatic tracking fingerscontacting the two edges of the music sheet and controlling the truetravel of the sheet; and in Fig. 2 is the same view with the hand rollregulator thrown into use and the automatic tracking fingers thrown outfrom the edges of the music sheet.

Two usual clutch spindles 1 and 2 are adapted to engage and revolve amusic roll 3 on which is mounted a music sheet as 4. Two verticaldetector fingers 5 and 6 are mounted on pivots 7 and 8, and have inwardly extended horizontal arms 9 and 10 which nearly meet, and at suchposition of adjacency cooperate with a valve seat 11 which is mounted onanother horizontal arm 12, pivoted co-axially with arm 10. All thesearms, 9, 10 and 12 are extended beyond these pivots 7 and 8, and on suchextensions are individual counterweights 13, 14, and 15. These severalweights are so arranged that when the detector fingers 5 and 6 are tocontact the edges of the music sheet 4 the pressure of the detectors 5and 6 will not be overstrong against that paper. Particular care istaken that the counterbalancing is so adjusted that the seat 11 willalways follow the inner ends of the arms 9 and 10, but that either onealone of the said arms 9 or 10 will have sufficient remaining weight toalways rest on the seat 11 when the other arm 9 or 10 is away from theseat 11 when the music sheet is-diverged from its central travel.

When the sheet 4 is truly central the two detectors 5, 6, and their arms9 and 10 both maintain contact with the seat 11, thereby controllingcertain ports connected to any usual pneumatic apparatus to actuate theshifting means to move the spindles 1 and 2 to the right or left tocompel the central travel of the sheets whenever it diverges therefrom,and thereby thrusts one or the other of the arms 9 and 10 away from theseat 11. The intermediate parts, as pneumatics, etc., are not hereshown, but are to be understood as having tubular connections from portsin the seat 11 to any suitable pneumatics, the latter having mechanicalconnections terminating by a rod 16 engaging a unitary means or yoke 17similar to applicants prior Patent #1,112,061 September 29, 1914, whichyoke engages the two spindles 1 and 2 and by suitable collars thereonand the spring 18 draws the two spindles together and thereby engagesthem with and holding the music roll 3, or any other suitable connectingand controlling means may be employed.

Whenever a music sheet is found that has its perforations cut out ofcenter to the correct travel line, or whose edges are too badly damagedto properly control the detectors 5, 6, the hand roll regulating devicescan be thrown into operation, and the detectors may also be spread apartand clear of the edges of the sheet, as in Fig. 2, as will now beexplained. v

The spindle 2 runs in a regulator bearing 19 threaded co-axiallytherewith into a support 20. While 'in a structure without an automatictracking device such a threaded regulator, bearing 19, would directlyregulate the position of the roll 3 by the said roll being pressedagainst the head 21 of the said spindle 2 and that head against the endof the regulator bearing, such a construc tion would interfere with theaction of an automatic tracking mechanism, which could not move thespindle 2 to the right because of the checking by its head 21 againstthe regulator bearing 19, wherefore the present structure has theregulator bearing-l9 of a length to clear the head 21 of the spindle 2so that the head 21 and its spindle'2 are freeto be longitudinally movedby the automatic tracking means 17, 16, etc., as described in par. 2 ofpage 1.

lVhen the hand regulating is desired,-the switch or throw-out handle 22is partly re volved with the shaft: 23 on which it is fixed asshown inFig. 2, thereby the circumferentially tapered cam 24- has its full widthpart broughtaround within a groove in the collar 25 attached on spindle2, which wide part ofthe cam 2 1- has a nice running and guidin-gfit tothe groove of the collar 25, thereby compelling the collar 25and spindle2 attached therewith, to maintain whatever position lengthwise of thespindle linethat the cam 24L andits attached shaft 23 may be set to bycontrol of a plain guide arm 26 and hub col-larfixed with the shaft 23,and guided by a groovehin a collar 27 attached toorna part of theregulator19 and revoluble with said bearing 19 and therebyshiftablelengtlr wise of the spindle line to regulate any defsiredtracking position of theroll 3 and its music sheet 4-, as shown bythe dotted lines in Fig- 2 indicating the rightward position of theregulator parts, thefull lines being the leftward positionlV-hen theapparatus has the switch handle 22 set for hand regulating,-which in thepresent showing is with the handle 22 thrown over to the front and down,an extension or arm 28 is pressed down on the head 29 of a vertical rod,80, which rod 30 stands over the counterweight 15 or other convenientand suitable part-of the seat arm 12, thereby depressing that outeraendof the seat arm 12 and raising these-at; 11,and thus lifting the twoarms 9, 10,'and, throwing apart the two detectorarms 5, 6, so that theirdetector parts, clear'theiedges of the musicsheet and thus'have-thesheet free, and avoid any actuating of the automatic tracking devicesagainst ,the setting of the spindles by the hand regulator, whichactuating at suchtiine would cause great-retarding or entire stopping ofthe spindles from the pressure of the automatic tracking motor meansagainst the {regulated spindle, WVhen the detectors 5, 6,,1are sospread,andatheseat 11 is in a raised p0sition,-both the arms 9, 10, are heldonithesaid seats, so that theentire automatic tracking devices are outofoperation, and

free for the longitudinal regulating of the spindle 2 by the handregulator 19. A spring 3lserves to hold the-rod 30, free from the weightl5 and arm 12 when the throw-out handle 22 is in position for r the Iautomatic tracker devices to operate.

hen the throw-out handle 22 is set for the operation of, the automatic.tracking des vices, the narrow part of the cam. 24L is between the sidesof the groove of the collar 25 so that the 'wider part of the cam may besure to follow to position in that groove when revolved to that positionby the handle .22 and the shaft, 23, but the difference in or apertures,and whether pneumatic, electric or mechanical power, or any combinationof powers, as pneumatic mechanical or the, like, but what I claim as my,invention 1s:
